TEE GLEVELAIN'D VELIFING- COMPANY, OF GLEVIELAND, OI-IIO, A CORIPOBA'LION O]? OHIO Application fi1ed. October 3, 1924. Serial N0. 741,329.

'ihs invencion relates genemlly to vehic1e wheels and m01'e particularly t9 a disk Whee1 having a tire carrying 1im demountably secured thereon.

The object of the invention is to provide a simple and eas'11y produced disk wheel of such construction that a demountable tire carrying rim can be quickly and easi1y mounted and demount-ed with a minimum amount of rim securing means.

Another object is 130 provide a disk wheel und ri.1n particularly adapted for use in comnection Wich balloon tires Which ca11 f01 whee1 boies o]? sma1ler iameter than the wheel bodies heretofore employed.

Vith these objects in view the invention consists in tne novel feat-uces 01: construotion und in the manner of combining or arranging fhe same, all of which will be fully described pointed 0ut in the appended claims.

In ths drawings forming a part of this specificaion Fig. 1 is a face view of a wheel body embodying one form -of my invention and Fig. 2 is a section on ehe 1ine 22 of Fig. l.

B-efe1ring t0 tne drawing-s A indicates the hub Which may be 013 any desired type and. provided with a hub flange A and a brake lrum B cam be conneced to this hub flange f0r oifhe1 front 01 raar wheel.

The .cody 0"E the wheel is a shee metal lisk (l, having a cent1al opening to receive the hub and the central ortion of this disk is t0 confonn to and contact With the A flange ring A is also nnploye t0 contac with the cent1al Portion f aisk an bolts A connect the hub and wh-sel disk and flange rings together und the brzxke drum can also be connected by these bolts :lf so desired.

T110 disk near its periphery is flat as shown at C and is then carried laterally inwardly and channeled as shown at C t0 rece'1ve the centml inwardly projectiny portion D 0f the tire carrying rim D, sai rim having 121re cngaging flanges D.

The deep centra1 groove D permits fche pushing inward 01' the tire casing bead, aiter deflation, and in this manner the casing can be removed, inasmueh as iccan be lifted c1ear of ehe rim at the side opposite th e point where th e bead is p ushed inwardly into the central depression 01 groove.

The chanheled periphery C of the disk C has an aperture t-0 receive the Valve stem and in line with this valve stem hole the disk is formed with an upset portion or shoulder C which Wih' the inner flange C forme; a sadd1e 01 se;1t into which the rim D (ran rast 2ind the rim is then' dropped down around the channeled periphery C there being Sufficient clearsince; and the rim is'then pushed laterally into place and secured by means of clamps E mounted u'pon b-olts F attached t0 ehe flat Portion of the disk at points substan tially 120 from the shoulder C anc1 from each other. Nuts G are arrzinged upon the bolts and force the clamps inwardly so that the outer wedge shaped ends E contact with rim base and f0rce the rim laterally inwardly and radia1ly outwardly und in this manner securely fastening the demountable rim 130 the disk whee1 body. The disk Can be flattened as shown a C clamps 130 bear upon if so desired.

A wheel body constructed in accordance with my present invention therefore includes a disk having a channeled periphera] porti-on with a shoulder ab 0ne point and clamping wedges at oppositely space points, the demountable 1im employed in connection Wiuh said wheel body having a centra1 inwardly projecting portion which seats in the channeled periphery behind the shoulder and is engaged by the outer ends 0f the clamping wedges for the purpose of tensionihg the rim upon the Whee1 body.

Having thus deseribed my invention, what I claim ist l. The combination with a disk having a channeled peripheryand provided with an outwardly projecting shoulder ab 0ne point ab the outer edge of said channeled periphery, of a demountable tire earrying rim having a relatively deep central inwardly projecting ortion adapted to seat in the channel 0f the periphery and spaced c1amps connected to the for the heels of the disk and adapted t0 engage the inwardly pro- 21100 jecting portion 0f the rim and tension the same upon the Wheel body.

2. The combination of a disk having a relatively deep channeled periphery and provided with an ouowardly projecting shoulder at one poincupon the outer edge of said channeled periphry a demountable tire carrying rim having a relatively deep central inwardly projgcting portion adapted to seat in the gh'mnel 0f the periphery, bolts carried by the disk adjacent the periphery and at points spaced from the outwardly projecting shoulder, clamping wedges arranged upon said bolts and nuts upon said bolts forcing said clamping wedges into engagement with the inwardly projecting portion ofthe rim and whereby said rim is tensioned upon the 'wheel body.

3. In a disk wheel the combination 0f a disk having a channeled periphery and provided wit-h an oucwardly projecting shoulder at the outer edge thereof and an inwardly und outwardly inclined flange on the inner edge thereof, of a demountable rim having a relatively deep inwardly projecting port10n seating in said channel und spaced c1amps connecfed to said disk anc% adapted 130 engage the iriwardly projeccing portion of said rim anal tension the same upon the Wheel body. In testimony whereof, I hereunto afiix my signature.
